Title: Constant voltage circuit
Inventor: OBUKA TERUTAKA
IPC: G05F1/10
Filed: 1988-06-06
Abstract: PURPOSE:To flow a current to a load without reducing the output voltage of a power source by providing a rush current by-pass circuit, which consists of a transistor TR for shunt circuit and a load current measuring resistance, and a power supply part. CONSTITUTION:When a large current like a rush current does not flow, the voltage drop of a load current measuring resistance 23 is set to a value lower than the voltage between the base and the emitter of a TR 22 for shunt circuit, and therefore, the base current does not flow. Consequently, the circuit between the emitter and the collector is turned off, and a rush current by-pass circuit 24 consisting of the TR 22 and the resistance 23 has not an influence on a power supply part 21 at all. However, when the load current is increased and the voltage drop of the resistance 23 exceeds a prescribed voltage, the base current flows by its excess voltage, and the current amplified approximately in proportion to this current flows through the emitter and the collector to form the circuit 24. That is, the current exceeding the prescribed value does not pass the power supply part 21 at all but passes the circuit 24, and thus, the current flows to the load without reducing the output voltage of the power source.

Title: Wire dot printer
Inventor: TAKANO HIROKUNI
IPC: G06K15/10
Filed: 1978-11-13
Abstract: PURPOSE: To lower the ink viscosity between a wire and a wire guide to perform a good printing by applying exciting pulses for a minute time, which drive the print wire within a range where the print wire does not print, to magnets.  
     CONSTITUTION: Timer 2 outputs a non-print signal when it is detected that print signals are not received for a fixed time, and at this time, timer 2 operates pulse generator 3 when a data present signal is received. Then, minute-time exciting pulses which drive the print wire toward the platen within a range where the print wire does not print are applied to magnets 8a, 8b...8n. Therefore, viscosity of ink filled up between the wire and the wire guide is lowered or this ink is pressed outside, and the print head completes print preparations. Next, character generator 1 applies signals corresponding to receiving data to magnets 8a, 8b...8n through driving transistors 5a, 5b...5n. Thus, printing is performed well.
